' GATE-MACHINE Specification of Letters Patent.

Patented Feb. 9, 1909.

Application filed January 17, 1908. Serial No. 4 11313.

cinnati, in the county of Hamilton and State of Ohio, have inventedcertain new and use-- ful Improvements in Cake-Machines, of which thefollowing is a specification.

My invention relates to that class of machines in which the cakematerial is placed.

in a hopper and fed by rollsthrough a die plate by which it is separatedinto formedv masses, out off, and dropped into pans ready for baking,and has for its object, first, to, provide a simple and efficient meansfor tipping the hopper over so that the rolls and die plate attachedthereto may be cleaned readily; second, to provide means for adjustingthe cutting off device to suit the requirements of various sized cakes;third, to provide means whereby the cutting off device may. be quicklydisconnected from its actuating mechanism for the purpose of effectingthe aforesaid adjustment.

I attain the above mentioned ob ects by the mechanism illustrated in theaccompanythe actuating mechanism for the cutting off Figure 1 is a sideelevation of the machine.

Fig. 3 is a plan view of the partsshown in Fig. 2. Fig. 4 is a partial transverse section through thehop-- per 6, showing the means used for tlppmg same. Fig. 5 is a planview of the machine. Fig. 6 is a vertical longitudinal section throughthe hopper. Fig. 7 is a similar view of hopper showing the position whentipped over. Fig. 8 is a detail plan view of the cutting off frameshowing how the cutting off wire is attached. Fig. 9 is an edge view ofthe parts shown in Fig. 8. Fig. 10 is a detail vertical section throughthe die plate, a side elevation of the cutting off frame and the shuttleoperating same. Fig. 11 is similar to Fig. 10, with the die plateomitted, showing the movement of the cutting off frame.

I have shown my invention mounted upon a suitable frame comprising apair of side.

frames, and journaled thereupon, is the shaft I 2, driven by the pulley3. Mounted upon each of said side frames is the bracket 4 provided withthe'bearing 5.

The hopper 6' is provided with a trunnion 7 on each end, rotatablymounted in said bearings 55. Through the center of said trunnion, andconcentric therewith, the shaft 8 revolves, carrying the feed roll 9,and driving the companion roll 10 by the gears 11 and 12. Secured to thebottom of said hopper 6 and central therewith and beneath the rolls 9and 10, is the die plate 13. The arms 1414 pivoted on the shaft 15 carrythe rod 16 upon which fingers 1717, 18-18 and 19 are mounted. Thefingers 17 and 18 are provided with serrations 20 cut in theirextremities which serve to hold a fine wire 21.

I have elected to style the assemblage of parts 16, 17, 18, 19, 20 and21, and their essential concomitants, the cutting-off device. The sleeve22 is pivotally mounted on arm 14 by the stud 23 and has slidablyconnected therewith the eccentric rod 24 secured to the eccentric 25,mounted on shaft 2. I have chosen to designate the parts 24 and 25 asdevice. The sleeve 22 is provided vwith a plunger 34, having the knob 35and compression spring 36 which holds said plunger in the hole 37 insaid eccentric rod.

When the machine is operating the cake material is fed by the rolls 9and 10 through the die plate 13, and when the proper amount of thematerial has been forced through said die plate the arm 14 actuated bythe eccentric rod 24 and eccentric 25 carries the cutting ofl' deviceforward with its cutting off wire 21 in close proximity with said dieplate and beneath same and in such operation the wire 21 cuts oif'theextending cake material and the same drops upon pans beneath. The extentof the movement of the cuttingoff device is fixed and predetermined bythe amount of eccentricity of the eccentric 25 and the arm 14 andconnecting parts, and is suflicient to enable the cuttingoff wire totravel the full width of the widest die plate. Such die plate 13 isshown in section in Fig. 10. IVhen die plates having wide openings areused, the cutting-off wire is placed on the end of the frame as shown inFig. 8. Then the cutting-off frame has completed its forward travel itis dropped and returns to its starting point in a lower plane, theforward and rearward movement of said frame being illustrated in Figs.10 and 11 respectively. This movement of the cutting-off frame isaccomplished by the arm 19 provided with the roller 27 cooperating witha shuttle device, comprising the casting 26 having the channel 28 inwhich the roller 27 travels in its return stroke and the angle plate 29pivoted at 30, over which angle plate said roller travels in its forwardmovement. This shuttle device is old and well known.

It is desirable to have the forms of cake material drop as soon as theyare cut off by the wire and such immediate dropping is facilitated byhaving the wire drop as soon as the cutting-off process is completed. Ihave discovered, by experiment, that in case the cutting-off wire doesnot drop as soon as the cake material is cut off, that the formedmaterial will cling to the wire and become disfigured thereby; but byhaving the wire drop suddenly as soon as the formed mate rial is cutoff, the downward motion of the wire greatly facilitates the dropping ofthe formed material and the same is deposited upon pans below in aperfect condition. Now since this machine is designed for various sizedcakes, including very large and very small ones, die plates with verywide and very narrow openings will be used. I have shown, in F 10, a dieplate with a very large opening and also, by dotted lines, one with avery small opening. IVhen dies with large openings are used thecutting-oft wire is placed at the extremities of the fingers 17 and 18,as shown in Fig. 8, but when dies with small openings are used the cutting-otf wire is placed around the hooks 31 in the position shown in dotand dash line in Fig. 8. By thus changing the position of thecutting-oil" wire to that shown by dot and dash line in Fig.8 when verysmall cakes are desired, the dropping movement of the wire will occur ator about the moment the cutting-01f process is completed and thusproduce the result desired and by placing the wire in the position shownby the full line in Fig. 8 it will drop at or about the proper momentwhen used to cut olf large cakes.

In case it is desirable to form cakes the length of which areintermediate between the aforesaid two extremes other hooks simi lar to31 may be inserted at any point on the fingers 17 and 18 between thatshown in Fig. 8 and the extremities thereof, as at 4:0, and by so doingthe wire may be given any po sition between the two extremes shown,towit, that shown by dotted line.

I have provided the hook 32 with the nut 33 for tightening the cuttingoff wire whether it is placed at the finger extremities or under thehooks 31-31. YVhen it is necessary to adjust the cutting-olt wire, tochange same from one position to the other, or to repair the wire,access to the same. greatly facilitated by raising the plunger 31 out ofthe hole 37 by taking hold of the knob 35 and thus disconnecting thecutting-ell device from its actuating mechanism and throwing back thearm 11- and thus withdrawing the cuttingoli' frame from beneath thehopper. The rolls 9 and 10 are provided with scrapers 38 and 39 whichserve to prevent the cake material from adhering to same.

Having fully described my invention, what I claim as new and desire tosecure by Letters Patent is:

1. In a cake machine the combination with feed rolls of a receivinghopper mounted upon the axis of one of said feed rolls and arranged tobe tipped over upon said axis.

2. In a cake machine the combination with feed rolls of a receivinghopper contiguous thereto and mounted upon the axis of one of said feedrolls and arranged to be tipped over upon said axis.
